Prognostic Value of CAR, AFR and Ferritin in Non-M3 AML

September 3, 2026 updated by: Aya Salah Noureldin, Assiut University

The Prognostic Significance of C-Reactive Protein to Albumin Ratio, Albumin to Fibrinogen Ratio, and Serum Ferritin Level in Newly Diagnosed De Novo Non-M3 Acute Myeloid Leukemia Patients

This prospective cohort study aims to evaluate the prognostic significance of the C-reactive protein-to-albumin ratio (CAR), albumin-to-fibrinogen ratio (AFR), and serum ferritin level in newly diagnosed de novo non-M3 acute myeloid leukemia patients at Assiut University Hospitals.

Study Overview

Detailed Description

Acute myeloid leukemia (AML) is an aggressive hematological malignancy with poor clinical outcomes. Inflammatory and nutritional biomarkers such as the C-reactive protein-to-albumin ratio (CAR), albumin-to-fibrinogen ratio (AFR), and serum ferritin have shown potential prognostic value in various malignancies.

This prospective single-center cohort study will include newly diagnosed de novo non-M3 AML patients aged 18 to 65 years. Baseline laboratory parameters including CRP, albumin, fibrinogen, and ferritin will be measured before induction chemotherapy. Patients will be followed for overall survival, event-free survival, and response to induction therapy. The study will assess the association of CAR, AFR, and serum ferritin with clinical outcomes.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall survival
Time Frame: Up to 24 months

Up to 24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Complete remission rate after induction chemotherapy
Time Frame: Day 28 after induction chemotherapy
Proportion of patients achieving complete remission after induction chemotherapy, defined as bone marrow blasts less than 5%, absolute neutrophil count greater than 1.0 × 10⁹/L, platelet count greater than 100 × 10⁹/L, and independence from red cell transfusions.
Day 28 after induction chemotherapy
Event-free survival
Time Frame: Up to 24 months
Time from diagnosis to the first occurrence of treatment failure, relapse, or death from any cause.
Up to 24 months
Prognostic value of C-reactive protein-to-albumin ratio (CAR)
Time Frame: Baseline and up to 24 months
Hazard ratio for overall survival and event-free survival according to baseline C-reactive protein-to-albumin ratio (CAR), calculated as CRP (mg/L) divided by serum albumin (g/L), using Cox proportional hazards regression.
Baseline and up to 24 months
Prognostic value of albumin-to-fibrinogen ratio (AFR)
Time Frame: Baseline and up to 24 months
Hazard ratio for overall survival and event-free survival according to baseline albumin-to-fibrinogen ratio (AFR), calculated as plasma fibrinogen concentration (g/L) divided by serum albumin concentration (g/L), using Cox proportional hazards regression.
Baseline and up to 24 months
Prognostic value of serum ferritin
Time Frame: Baseline and up to 24 months
Hazard ratio for overall survival and event-free survival according to baseline serum ferritin level (ng/mL, corrected if CRP is elevated), using Cox proportional hazards regression.
Baseline and up to 24 months
